Abstract

1,175,174. Keyboards. KIENZLE APPARATE G.m.b.H. 15 March, 1968 [18 March, 1967], No. 12689/68. Heading G4H. Operation of a key 53, Fig. 3, causes temporary raising of magnetic pins 93-96 through holes in plates 101-103 carrying a primary printed circuit conductor P 1 -P 4 and secondary printed circuit conductors S 1 -S 8 , a flag 122 passing between light source 124 and photo-cell 125 providing an energizing pulse for primary P 1 -P 4 . The arrangement of conductors S 1 – S 8 is such as to give a combination of outputs unique to the associated key 53. A latch 861, 651 effects release of the pins 93-96 before key 53 has been fully depressed to allow another key to be pressed as soon as arm 80 swings clear of ball lock 118. The associated circuitry is shown in Fig. 9. Two further keys 51, 52 are provided for keys representing two characters and for instructions respectively. When key 51 is pressed at the same time as a double character key, bit A5 is complemented and half-adder 146 corrects the parity bit A 7 .
